* Opel/Vauxhall: These European brands, owned by GM (though not part of the US GM), produce cars primarily in Europe. Many models are not sold in the US.
* Buick (some models): While some Buicks are made in the US, some models are produced in China for the Chinese market and may be exported elsewhere.
* Cadillac (some models): Similar to Buick, certain Cadillac models might be produced in China or other international locations.
* Chevrolet (some models): Chevrolet has a significant international presence. Various models are built in Mexico, Canada, South Korea, and other countries.
To know definitively if a *specific* GM car model and year is made in the USA, you'd need to check the vehicle's sticker (often found on the driver's side door jamb), the GM website, or a reputable automotive resource. Simply stating a model name (like "Chevrolet Malibu") isn't sufficient because production location can vary.
